 An exclamation mark in a triangle indicates important notices in these operating instructions which have

to be observed under all circumstances!

 The triangle containing a lightning symbol warns of danger of an electric shock or of the impairment of the

electrical safety of the device.

 The “arrow” symbol indicates special information and advice on operation of the device.

This product has been CE-tested and meets the necessary European guidelines.

Class 2 insulation (double or reinforced insulation)

CAT II Measuring category II for measurements on electric and electronic devices connected to the mains sup-

ply with a power plug. This category also covers all smaller categories (e.g. CAT I for measuring signal

and control voltages).

CAT III Measuring category III for measuring in building installation (e.g. outlets or sub-distribution). This category

also covers all lower categories (e.g. CAT II for measuring electronic devices). Measuring operation in

CAT III is only permissible with cover caps at the measuring prods.

CAT IV Measuring category IV for measuring at the source of the low-voltage installation (e.g. main distribution,

house-transfer points of energy providers, etc.).

Ground potential

The unauthorised conversion and/or modication of the unit is inadmissible because of safety and approval reasons

(CE).

Consult an expert when in doubt about the operation, the safety or the connection of the device.

Measuring instruments and accessories are not toys and have no place in the hands of children.

On industrial sites the accident prevention regulations of the association of the industrial workers’ society for electri-

cal equipment and utilities must be followed.

In schools, training centres, computer and self-help workshops, handling of measuring instruments must be super-

vised by trained personnel in a responsible manner.

The voltage between the measuring instrument connection points and earth must never exceed 250 V DC/AC in

CAT III.



When using the measuring lines without cover caps, measurements between the

meter and the earth potential must not be performed above the measuring category

CAT II.

When measuring in the measuring category CAT III, the cover caps must be pushed

onto the measuring prods to avoid accidental short circuits during measurement.

Push the cover caps onto the measuring prods until they latch. To remove them, pull

the caps from the prods with a little force.

The test prods have to be removed from the measured object every time the measur-

ing range is changed.

Be especially careful when dealing with voltages higher than 33V AC or 70 V DC. Even at such voltages you can

receive a life-threatening electric shock when you come into contact with electric wires.

Check the measuring device and its measuring lines for damage before each measurement. Never carry out any

measurements if the protecting insulation is defective (torn, ripped off etc.) Measuring cables have a wear indicator.

When they are damaged, a second insulation layer in a different colour becomes visible. The measuring accessories

must no longer be used and must be replaced.

To avoid an electric shock, make sure not to touch the connections/measuring points to be measured neither directly

nor indirectly during measurement. During measuring, do not grip beyond the tangible grip range markings present

on the test prods.

Do not use the multimeter just before, during or just after an electrical storm (electrical shock / high-energy overvolt-

age!). Please make sure that your hands, your shoes, your clothing, the oor, switches and switching components

are dry.

Avoid an operation near:

- strong magnetic or electromagnetic elds

- transmitter aerials or HF generators,

Since this could affect the measurement.

If you have a reason to believe that the device can no longer be operated safely, disconnect it immediately and

secure it against being operated unintentionally. It can be assumed that safe operation is no longer possible if:

- the device is visibly damaged,

- the device does not operate any longer and

- the device was stored under unfavourable conditions for a long period of time or

- it has been subjected to considerable stress in transit.

Do not switch the measuring instrument on immediately after it has been taken from a cold to a warm environment.

The condensation that forms might destroy your device. Leave the device switched off and wait until it has reached

room temperature.

Do not leave the packaging material lying around carelessly since such materials can become dangerous toys in the

hands of children.

You should also heed the safety instructions in each chapter of these instructions.

The multimeter (referred to as DMM in the following) indicates measured values on the digital display. The measur-

ing value display of the DMM spans 2000 counts with VC130-1 and VC150-1 as well as 4000 counts with VC170-1

(count = smallest display value). The VC170-1 sets the right measuring range automatically (AUTO range). How-

ever, manual selection of the measuring range is still possible.

The measuring device can be used for do-it-yourself or for professional applications (up to CAT III 250V).

For better readability, the DMM can also be mounted with the clip on the rear.

The DMM VC130-1 and VC150-1 are turned on and off via the button “POWER”. When the rotary switch is set to

“OFF”, the VC170-1 is turned off. Always turn the measuring device off when it is not in use.

Prior to working with the measuring device, you rst have to insert the enclosed batteries.

Insert the battery as described in the chapter “Cleaning and Maintenance”. A 9V block battery is required for voltage

supply. This is part of the delivery.

- Turn the DMM on and select measuring range “Ω”.

- Insert the measuring cables in line with the model into the corresponding measuring sockets as shown in the

table.

- Check the measuring leads for continuity by connecting both measuring prods to one another. After that the resist-

ance value must be approximately 0.5 Ohm (inherent resistance of the measuring leads).

- While the measuring tips are short-circuited, press the button “SELECT” (only with the VC170-1)) to not let the

inherent resistance of the measuring leads ow into the following resistance measuring. The display shows 0 Ohm

- Now connect the measuring prods to the object to be measured. As long as the object to be measured is not high-

resistive or interrupted, the measured value will be indicated on the display. Wait until the display has stabilised.

With resistances of >1 MOhm, this may take a few seconds.

- If “overload” appears on the display, you have exceeded the measuring range or the measuring circuit is inter-

rupted.

- After measuring, remove the measuring leads from the measuring object and turn the DMM off. Turn the rotary

switch to the position “OFF” or turn the device off via the “POWER” switch.

 If you carry out a resistance measurement, make sure that the measuring points which you contact with the

measuring prods are free from dirt, oil, solderable lacquer or similar. An incorrect measurement may result

under such circumstances.

- Insert the measuring cables in line with the model into the corresponding measuring sockets as shown in the

table.

- Check the measuring leads for continuity by connecting both measuring prods to one another. After that the value

must be approximately 0 V. The open-circuit voltage is approx. 3 V.

- Now connect the two measuring prods with the object to be measu-red (diode).

- The display shows the continuity voltage in volt (V).

- If the symbol for “overload” is shown the diode is measured in the locking direction

or the diode is defective (interruption). Perform a counter-pole measuring for control

reasons. The red measuring lead corresponds to the positive pole (anode), the black

measuring lead to the negative pole (cathode). A silicone diode has an on-state volt-

age of approx. 0.5 – 0.8 V.

- After measuring, remove the measuring leads from the measuring object and turn the DMM off. Turn the rotary

switch to the position “OFF” or turn the device off via the “POWER” switch.
